PACKAGE FOR MERCURY, &C.

SPECIFICATION forming part of Letters Patent No. 231,740, dated August 31, 1880. Application inea June 2s, issn. (No model.)

To all whom it may concern Be it known that I, RICHARD S. WILLIAMS, of the city, county, and State of New York, have invented a new and Improved Package for Mercury, 85o.; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making part of this specitication. l

The invention is, as a new article ot' manufacture, a device for containing mercury for dental purposes, or other substances, consisting of a strip of suitable material having a series of cells formed therein, and of a sealingcovering for the cells, which is easily detachable from each cell independently of the other cells, as is hereinafter more particularly described.

In the accompanying sheet of drawings, Figure l represents a plan or top view ot my package with covering part-ly removed; Fig. 2, a longitudinal section of same in line a' x, Fig. l; and Fig. 3, a lcross-section, enlarged, in the line y y, Fig. 2.

Similar letters of reference in dicate li ke parts in the several gures.

Dentists in the course-oi' their practice have occasion to employ mercury in the preparation of their amalgams, and this has heretofore been contained in a bottle, into which is pierced a small hole, through which hole the mercury is forced by the proper manipulation of the bottle, but this contrivancea'ords no guide or limit to the 4amount used, except general experience or guess-work. Therefore the dentist may use too much mercury and produce an amalgam from which the mercury will ooze from time to time, or he may have too small a quantity, and his amalgam not be sufciently plastic for the purpose of iilling the dental cavities. In other words, in order to produce a proper amalgam, the quantity of mercury must be in a given proportion to the quantity of metal iilings with which it is incorporated.

To arrive at this desirable result in an expeditious and convenient manner, l prepare a strip of wood, hard rubber, glass, or other suitable material, A, by forming therein a series of cells, a, each cell having the capacity to hold a given quantity of mercury, c. The niercury may be placed in these cells by immersing the strip in a bath of mercury or in any desirable manner.

the strip over, and the dentist at once dis-V lodOes a iven uantitv of mercur which he s g .i7

can employ for his amalgam, and, by using thel metal filings for this amalgam in the manner described in the specification ot' an application for a patent led simultaneously herewith, he can employ a given quantity of metal tlings with a given quantity ot' mercury, and in this way with' certainty produce`tl1e best amalgam in every instance that the materials will admit.. Besides, bythe employment ot' the fbregoing-described package the mercury is kept free from dust and oxidation.

Other means may, perhaps, bc employed for measuring a given quantity ot'- mercury, such as a graduated tube of glass; butthe contrivance herein described will be found the most convenient.

rlhe strip A, if desired, may be divided into sections by'lines c. The cells a being located in the center between each of these dividinglines will enable the user to readily ascertain the exact location of each cell before fracturing the cover of the cell for use.

It is obvious that my invention may be 'employed vto contain medicines or other substances.

Having now described my inventionpwhat I claim as new, and desire to secure by Letters Patent, is-

As a new article ot' manufacture, a device for containing mercury for dental purposes, or other substances, consisting of a strip of suitable material having a series of cells formed therein, and of a sealing-coverin g for the cells, which is easily detachable from each cell independently ot' the other cells, substantially as and for the purposes described.
